Nikon needs to make a constant f/4 tele

Basically I was suggesting it would be nice if there was a full "Trinity" of enthusiast oriented f/4 zooms like there is for the Pro f/2.8 zooms (basiscally an enthusiast f/4 constant aperture version of the 70-300 VR). It would also need to be enthusiast in terms of cost like the 16-35 and 24-120, roughly 2/3 the price of the pro equivalent, give up a little IQ and a stop of aperture in exchange for a slightly larger range and lighter weight. The 200-400 f/4 is a $6,750 pro exotic lens and is a continuation of the pro lineup.

The 300 f/4 is a prime so it would not fit this category, although it is certainly a lense that I would be interested in purchasing, especially if they update it with VR.
